Learn about the development of the domestic weighing
China's transition from a planned economy to a market economy has also brought about changes in social demand and consumption trends. For example, since the 1990s, the form of sales in China ’s economic circulation has changed. Bulk and unpackaged sales have been gradually replaced by “pre-packaged products”, which are convenient, clean, time-saving and diverse. The colorfulness of packaging and packaging has won the favor of many consumers. With the growth of market demand and the change in consumer trends, weighing instruments and other weighing instruments, as a modern measurement method for online measurement of packaging products, are becoming more and more popular among business people and The attention of the metrology department. This automatic weighing instrument is widely used in industries such as food and pharmaceutical fine chemical logistics distribution centers due to its high technical content and unique automatic feedback adjustment function.
China's weighing instrument industry is a traditional industry with a long history of development and an important basic industry. For many years, it has been dominated by mechanical weighing instruments. The 1980s began to expand the use of electronic weighing instruments and the development of large-scale automatic weighing instruments, but its degree of intelligence compared with similar foreign products, there is a certain gap. The low technical content of products is an obstacle for China to enter the international market, making it difficult for China to obtain international benefits.
In today's world economic integration, China can no longer protect domestic industries with 'high tariff' barriers. Only through international technology transfer, international technology exchange, and international capital flow of talents can we equip China's weighing companies to promote products Modernization is pushed to the international market. The advancement of this modernization process is also constrained by the social demand structure, consumption tendency, consumption structure, technological progress, and international trade.
Today's industrial production and daily life are inseparable from weighing, and with the development of production, people's symmetrical weight precision requirements continue to increase, especially in packaging, food, chemical, pharmaceutical and other industries, all require higher 'S weighing accuracy. The high-precision weighing device realized by the mechanical structure is not only complicated in structure, but also the support (knife edge and tool holder) is weak and easy to wear and rust. It has strict requirements on the working environment and large maintenance workload. Slow, low efficiency, can not meet the needs of production development.
In order to overcome the above shortcomings, in the 1960s, people developed an electromechanical electronic scale, which is composed of a lever system, a grating device and an electronic circuit. The lever system generates a displacement under the load. The grating device converts this displacement into a digital signal and sends it to the electronic circuit. After the combination is called the manufacturer, the digital instrument displays the weight value. The combination scale manufacturer's scale has improved accuracy than the mechanical lever scale and is more convenient to use. The weight value can be visually displayed by numbers and the weighing signal can be transmitted over a long distance.
